TORONTO, July 31 (Reuters) - Canada's main stock index
tumbled on Thursday after a default by Argentina stoked worries
about other emerging-market economies, while shares of Valeant
Pharmaceuticals International dropped sharply after the
drugmaker cut its outlook.
The Toronto Stock Exchange's S&P/TSX composite index
unofficially closed down 194.08 points, 1.25 percent,
at 15,330.74. Nine of the 10 main sectors on the index were in
the red.
